Current vector control based on average capacitor voltage strategy and hybrid modulation applied to the control of a 7-level PUC three-phase inverter

This paper presents a vector control system for the control of the capacitor voltages of a 7-level Packed-U-Cell (PUC) three-phase inverter. Usually, PUCs in a three-phase system are controlled as isolated systems. As a result, three voltage loop and three load current loops are required to control the capacitor voltage in each PUC. Additionally… CONTINUE READING
